Effect of Exercise Training on Rate Pressure Product in Ischemic Heart Disease

Purpose: This study was conducted to investigate the effect of aerobic exercise program on rate pressure product after rehabilitation of ischemic heart disease patients. Subjects: Thirty male patients were selected from the out patient clinic of the National Heart Institute participated in the study. Their mean age was 55±3.4 years and the mean ejection fraction was 40-45%. They suffered from hypertension and limited exercise tolerance from two years ago. Methods: All patients were evaluated by maximal exercise test before and after six months (24 weeks) of training. The measuring parameters included resting rate pressure product with mean 9476.78±230.8 beat/min. mmHg, resting systolic blood pressure with mean 123.46±13.34 mmHg and resting heart rate with mean 76.76±11.06 beat/min.. All participants received aerobic training program at 40% of peak oxygen consumption in the form of cycle exercise training. Results: The post treatment results of the study revealed significant reduction in the rate pressure product. Discussion and conclusion: Aerobic exercises at 40% of peak oxygen consumption can be considered as an effective intervention in rehabilitation of ischemic heart disease patients.
